Keyframing and TImeline suggestions

Based on almost a month of Sencha usage, I came up with the following suggestions

1. Adding a keyframe to existent animation
Now when you want to add a keyframe between two keyframes by double-clicking the timeline it just moves the previous one to the point you clicked.
So the top point is - I'd like to add any amount of keyframes between any two keyframes and manipulate them the way I want.

2. Animating multiple properties on a timeline
An object should have a separate timeline for each of properties animated, nesting is ridiculuos

3. Moving keyframes on a timeline
I'd like to see a feature of moveing any amount of keyframes of any amount of properties over timeline. It's good when you have to change overall timing of animations.

4. Motion and speed graphs
Custom easing graphs is good but what is really necessary is motion graphs for better, smoother animation

5. Graphical editing of motion path
The best example is Adobe After Effects or Flash where you can define a custom path of any complexity for an object.

Major Ditto on all five of these.

Sencha is probably the best CSS3 animation tool on the market so far. Implementing these five things would clinch things in terms of usability for developers.

On a side note, I also have to say I'm dismayed by the vast swaths of feature requests which have hundreds of forum views but zero answers from anyone, including the development team. I know you guys are busy, but it doesn't exactly bode well. (Some requests are kind of confused, but many are highly intelligent and constructive.) It would be nice to see a response.

Thanks for the feedback and suggestions.
We do regularly read and follow the Feature Request part of the forum, but you probably got a point that we could be better to at least acknowledge when we have read them.
